a week ago or so I noticed some strange noise coming from our
Nanoscope IIIa "E"-Scanner. It sounds a little bit like a clatter of an
old-fashioned self-timer.
In addition to this, I wasn't able to adjust the A-B/A+B as well as
the (A+C)-(B+D)/A+B+C+D. The A-B/A+B value was constantly increasing or must
I say decreasing from -2.0V to eg -9.0V!?
Trying to engage the cantilever during this phase, I will lost the
Sum-Signal totally.
All this happened in Contact mode.
We use the Nanoscope IIIa, together with the "E"-Scanner. 

Any suggestions, what kind of failure this could be?
What can we do, to bring this fine machine again to "life"?
